The use of substituted amides of structure (I) for modulating the activity of 11 .beta.-hydroxysteroid dehydrogenase type 1 (11 .beta.HSD1) and the use of these compounds as pharmaceutical compositions, are described. Also a novel class of substituted amides, their use in therapy, pharmaceutical compositions comprising the compounds, as well as their use in the manufacture of medicaments are described. The present compounds are modulators and more specifically inhibitors of the activity of 11 .beta.HSD1 and may be useful in the treatment, prevention and/or prophylaxis of a range of medical disorders where a decreased intracellular concentration of active glucocorticoid is desirable. ##STR00001##
